Iron carbide diagram is a graphical representation of the phases of iron and carbon at different temperatures and compositions.

• Also known as the Fe-C diagram, it shows the transformation of iron from ferrite to austenite to cementite as carbon content increases.

• The diagram is used to predict the microstructure and properties of steel based on its composition and heat treatment.

• The eutectoid point on the diagram represe...read more

A stress-strain curve shows the relationship between stress and strain in a material.

• The curve typically has three regions: elastic deformation, plastic deformation, and fracture.

• In the elastic region, the material returns to its original shape when the stress is removed.

• In the plastic region, the material undergoes permanent deformation.

• The fracture point is where the material breaks.

• The slope of the curve in the elas...read more

Hydraulic systems use fluid to transmit power and are commonly found in machinery and equipment.

• Understand the basic principles of hydraulic systems, including Pascal's Law and how pressure is transmitted through a confined fluid.

• Learn how to operate hydraulic equipment safely, including proper use of controls and understanding potential hazards.

• Regularly inspect hydraulic systems for leaks, damage, or other issues tha...read more

Pneumatic systems use compressed air to transmit power, while hydraulic systems use fluid (usually oil) to transmit power.

• Pneumatic systems use compressed air as the medium for power transmission.

• Hydraulic systems use fluid (usually oil) as the medium for power transmission.

• Pneumatic systems are typically used in lighter applications, such as air brakes in vehicles.

• Hydraulic systems are used in heavier applications, su...read more
